1.5. SIGNALS

 "NO CHANGE" SIGNAL
This is programmed from the coin box, depending on each manufacturer. In most cases, if
the machine has no change, it will only accept coins that go to return tubes.
 "NO ORANGES" SIGNAL
If the photocell on the right of the roller conveyor sees no oranges (Fig. 40), it starts the
loader and this is stopped when it sees oranges fall. If, however, the loader is working for 1
minute and the photocell continues to see no oranges, it signals "no oranges" and the
machine becomes out of service.
 "NO GLASSES" SIGNAL
When the service is started, the process is as follows: The glass loader (Fig. 19) releases a
glass and if the glass photocell (Fig. 39) sees no glasses, it repeats the operation three
times and, if it continues to see no glasses, it signals "no glasses" and the machine
becomes out of order.
"WITHDRAW GLASS" SIGNAL

Whenever there is something in front of the glass photocell (Fig. 39), this signal is lit up.
 "SELF-CLEANING" SIGNAL
This signal is lit up during the cleaning and draining process.
 "FAULT" SIGNAL
This lights up in the following cases:
- If, during a service, the oranges get stuck on the rollers and the squeezing machine
carries out 5 cycles without any oranges reaching the MAGNETIC SENSOR (Fig. 31).
- If, when starting or finishing a service, the glass conveyor, (Fig. 32) on its run, takes
over 8 seconds to reach the end of the run.
- If the squeezing machine (Scheme 1, No. 5) is blocked by something.
- If at any time the squeezer safety circuit is opened, which implies leaving the
SQUEEZING TRAY out of place or tripping the motor heat switch.
